Re: [vpp-dev] Write simple program that can work with VPP API

[Dave Wallace]

Samuel,

Your main() function is missing the initialization of the connection to 
VPP as well as vppinfra initialization should you decide to use such 
features in your app.


I would recommend that you review the vat (VPP API Test) application 
main() function which is the application used to test the vpp api c 
interface: https://git.fd.io/vpp/tree/src/vat/main.c


Thanks,

Re: [vpp-dev] How can i use VPP as MPLS PE/P device

Thanks, Ray. Do you know if HC BGP supports EVPN? Also, is there current or
planned OSPF and LDP support in HC?

Re: [vpp-dev] How can i use VPP as MPLS PE/P device

[Marek Gradzki -X (mgradzki - PANTHEON TECHNOLOGIES at Cisco)]

Hi,

just some clarification regarding honeycomb and MPLS.

HC does not populate Linux MPLS table currently.

VPP MPLS configuration support is planned for 18.01:
- Netconf/Restconf - already done:
https://gerrit.fd.io/r/#/q/topic:mpls+project:hc2vpp
https://git.fd.io/hc2vpp/tree/docker/mpls_demo

- BGP (rfc3701 + draft-ietf-idr-bgp-prefix-sid): in progress

Regards,
Marek

At the moment - there is no direct/easy way to do this AFAIK.

Router plugin is the best example of this, the other option is to use HC 
instead of FRR for BGP.

Dear Nikhil,

The first step in adding a new platform: construct 
.../build-data/plaforms/xxx.mk. There are several examples.

Note the rule:

xxx_native_tools = vppapigen

This rule builds the missing build-host tool.

Then:

“make PLATFORM=xxx TAG=xxx_debug vpp-install” or similar.

Caveat: the main Makefile “.../build-root/Makefile” is non-trivial.

In the past, we’ve used it to self-compile full toolchains, and to use the 
resulting toolchains to cross-compile embedded Linux images with squashfs / 
unionfs disk images.

All of the mechanisms are there to do interesting things, but since we seldom 
do those things anymore you can expect a certain amount of trouble.

Yeah so I am wondering what's the right approach on fixing it, I see
three alternatives:

1) "set" the new inacl even if there is an existing one applied..
upside: consistent with what "set" means in layman's terms; downside:
bigger change vs. the existing semantics which maybe is masking some
other issues.

2) return an error rather than zero, and let the callers deal with
this. upside: no big change of the semantics. downside: returning an
error might upset some callers that were "accidentally" relying on
this behaviour.

3) stick in a "clib_warning()" saying "This will soon return an error.
The calling code needs to ensure this is handled correctly", and wait
for one or two releases, and have a JIRA for the next release to
*then* do (2) in the next release.

If this behavior has been here sufficiently long, (3) seems like a
safest action..

What do you think ?

Re: [vpp-dev] Measure plugin performances

[Kinsella, Ray]

Justin,

Suggest adding vpphost and iperfvpp to different network namespaces.
All that is happening at the moment is the kernel is recognizing it owns 
both IPs and bypassing everything.


You also need to add vppiperf and vppout to a bridge domain in VPP.

Take a look at VPP bootstrap in vppsb, it does 98% of what you are 
trying to do here.

Actually, based on this link ( 
https://wiki.fd.io/view/VPP/Progressive_VPP_Tutorial#Exercise:_Connecting_two_vpp_instances

Here is how it looks like (hope format doesn't get scratched here):

  10.10.1.2/24
   |
   |
   |
vpphost (CLIENT)
  10.10.1.1/24

And here is the VPP-topology-building procedure:

## BEGIN ##
## create vpp and connect it to host
sudo vpp unix { log /tmp/vpp.log cli-listen /run/vpp/cli-vpp.sock } api-segment 
{ prefix vpp } plugins { plugin dpdk_plugin.so { disable } }

# veth interface between host and vpp
sudo ip link add name vppout type veth peer name vpphost
sudo ip link set dev vppout up
sudo ip link set dev vpphost up
sudo ip addr add 10.10.1.1/24 dev vpphost

# host interface between host and vpp
sudo vppctl -s /run/vpp/cli-vpp.sock create host-interface name vppout
sudo vppctl -s /run/vpp/cli-vpp.sock set int state host-vppout up
sudo vppctl -s /run/vpp/cli-vpp.sock set int ip address host-vppout 10.10.1.2/24

## create iperf server and connect it to vpp
sudo ip link add name vppiperf type veth peer name iperfvpp
sudo ip link set dev vppiperf up
sudo ip link set dev iperfvpp up
sudo ip addr add 10.10.2.2/24 dev iperfvpp

#disabled
#sudo ip route add 10.10.2.0/24 via 10.10.1.2
#sudo ip route add 10.10.1.0/24 via 10.10.2.1
## END ##

When running iperf:

# server bound to iperfvpp (10.10.2.2)
iperf3 -s -B 10.10.2.2 -D
# client
iperf3 -c 10.10.2.2 -B 10.10.1.1 -u -4 -k 10

It works but there is no trace of those packets inside VPP. Note: pings work 
and I'm able to see them inside VPP. What am I missing ? I think I can guess 
what the problem is but still don't know how to solve it. Any tips/help ?

Re: [vpp-dev] Measure plugin performances

[Justin Iurman]

Oh and by the way, when I say "Pings work" I mean "pings on vpp interfaces" and 
that's the only way I can see packets in VPP (which is normal after all). But 
still, pings to 10.10.2.2 work but no trace in VPP (same as iperf packets). 
Just wanted to clarify this, because it was a bit unclear.

[vpp-dev] Measure plugin performances

[Justin Iurman]

Hi everyone,

Just wanted to know if there is already something inside VPP to measure some 
metrics when testing performances of our own plugin ? I know there are some 
useful info with "vppctl show ..." but is it enough/all ?

Actually, based on this link ( 
https://wiki.fd.io/view/VPP/Progressive_VPP_Tutorial#Exercise:_Connecting_two_vpp_instances
 ), I was trying to reproduce the almost-the-same topology combined with iperf. 
Here is how it looks like (hope format doesn't get scratched here):
  _   __
 | |host-vppiperf   iperfvpp |  |
 |   VPP   |--- 10.10.2.1/24 --- 10.10.2.2/24 ---|  SERVER  |
 |_| |__|
  |
  host-vppout
 10.10.1.2/24
  |
  |
  |
vpphost (CLIENT)
 10.10.1.1/24

And here is the VPP-topology-building procedure:

## BEGIN ##
## create vpp and connect it to host
sudo vpp unix { log /tmp/vpp.log cli-listen /run/vpp/cli-vpp.sock } api-segment 
{ prefix vpp } plugins { plugin dpdk_plugin.so { disable } }

# veth interface between host and vpp
sudo ip link add name vppout type veth peer name vpphost
sudo ip link set dev vppout up
sudo ip link set dev vpphost up
sudo ip addr add 10.10.1.1/24 dev vpphost

# host interface between host and vpp
sudo vppctl -s /run/vpp/cli-vpp.sock create host-interface name vppout
sudo vppctl -s /run/vpp/cli-vpp.sock set int state host-vppout up
sudo vppctl -s /run/vpp/cli-vpp.sock set int ip address host-vppout 10.10.1.2/24

## create iperf server and connect it to vpp
sudo ip link add name vppiperf type veth peer name iperfvpp
sudo ip link set dev vppiperf up
sudo ip link set dev iperfvpp up
sudo ip addr add 10.10.2.2/24 dev iperfvpp

sudo vppctl -s /run/vpp/cli-vpp.sock create host-interface name vppiperf
sudo vppctl -s /run/vpp/cli-vpp.sock set int state host-vppiperf up
sudo vppctl -s /run/vpp/cli-vpp.sock set int ip address host-vppiperf 
10.10.2.1/24

#disabled
#sudo ip route add 10.10.2.0/24 via 10.10.1.2
#sudo ip route add 10.10.1.0/24 via 10.10.2.1
## END ##

When running iperf:

# server bound to iperfvpp (10.10.2.2)
iperf3 -s -B 10.10.2.2 -D
# client
iperf3 -c 10.10.2.2 -B 10.10.1.1 -u -4 -k 10

It works but there is no trace of those packets inside VPP. Note: pings work 
and I'm able to see them inside VPP. What am I missing ? I think I can guess 
what the problem is but still don't know how to solve it. Any tips/help ? 
Thanks !

Justin

Re: [vpp-dev] How can i use VPP as MPLS PE/P device

[Kinsella, Ray]

At the moment - there is no direct/easy way to do this AFAIK.

Router plugin is the best example of this, the other option is to use HC 
instead of FRR for BGP.

So, for the control plane, we can use e.g., FRR that will populate 
Linux's FIB and MPLS table. Then, we need to sync this info to VPP's 
FIB and VPP's MPLS table.


While the "router plugin" provides support for FIB synchronization, 
there is no support for MPLS sync. Does anyone know if there are plans 
to add this MPLS support to router plugin? Otherwise, what would be 
the alternative best way of synchronizing Linux MPLS table with VPP?


Thanks!
Michael.

If this is meant to refer to the VPP NAT plugin that is in plugins/nat

Our Jenkins jobs for 1710 are doing well.

Please revisits settings.xml section of the build guide
or build honeycomb from stable/1710 branch before building hc2vpp.

[vpp-dev] ACL Plugin: check for null session

[khers]

Dear VPP folks,

The get_session_ptr function may return null pointer, while we do not check
this situation in code, for example fa_node.c line 1029, if the sess equals
null, we get segmentation fault in next usage of sess.
Please share your thought about this.
